Recruiting studies
- NCT05384288Recruiting
How kids with blood cancers respond to the flu vaccine
This study looks at how children with blood cancers respond to the seasonal flu shot. It may help doctors understand what protection the vaccine provides for pediatric oncology patients.
Memphis, TennesseeAges Up to 18 years - NCT06841913RecruitingPhase 4
Woodsmoke, flu, and your nasal immune response
This study tests how breathing woodsmoke affects your nose's ability to fight off the flu virus. You will be exposed to woodsmoke and then given a live flu vaccine to see how your immune system responds.
Chapel Hill, North CarolinaAges 18–49 - NCT07111078RecruitingPhase 1
New Flu Vaccine (Stem) with or without Booster
This trial tests a new type of flu vaccine that targets a part of the virus that doesn't change much (the stem). It is given with or without a special booster, and researchers want to see if it provides broader protection against different flu strains.
Bethesda, MarylandAges 18–50 - NCT07651761Enrolling by invitation
Vaccine Talk Training for Primary Care Doctors
This study tests whether special training helps primary care doctors have better conversations with patients about flu and COVID-19 vaccines. You may be eligible if you're a patient who visits a participating clinic during the 2026–2027 vaccine season.
Worcester, MassachusettsAges 18 years+ - NCT07203755RecruitingPhase 1
Combination vaccine for whooping cough, Hib, and meningitis
This trial tests a new combination vaccine that protects against whooping cough, Haemophilus influenzae type b (a cause of meningitis and pneumonia), and several types of meningococcal disease (a cause of meningitis and bloodstream infections). It may help reduce the number of shots needed for children.
Shangqiu, HenanAges 2 months–6 years - NCT05291676RecruitingPhase 2
Study how vaccines work in aging and frailty adults
This trial studies how well your immune system responds to a vaccine in people who are younger adults or, especially, older adults and those with frailty. Your participation may help researchers understand why vaccine responses can differ with age.
New Haven, ConnecticutAges 21 years+ - NCT06333275Recruiting
Boosting immunity after CAR-T therapy
This trial checks if giving vaccines after CAR-T cell therapy can help your immune system fight off preventable diseases. It is for adults with certain blood cancers who are about to get CAR-T treatment.
BernAges 18 years+ - NCT07516418RecruitingPhase 1
RSV and Flu H5 Vaccine Formulations Study
This study tests different versions of experimental vaccines designed to protect against RSV (a common respiratory virus) and flu H5. You'll receive one of these vaccines and be monitored to see how safe it is and how your body responds.
Griffith, QueenslandAges 18–49
Common questions
- Are there clinical trials studying Influenza vaccine?
- Yes. Clin2 currently lists 56 recruiting studies that include Influenza vaccine, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Influenza vaccine trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Influenza vaccine an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Influenza vaccine or a specific trial is right for you.
